Dies ist ein informelles Treffen für Lernende, die ihre ersten Schritte in der Programmierung machen oder ihre Grundkenntnisse vertiefen möchten. *** This is an informal meetup, for learners that want to do their first steps in programming or want to consolidate their skills. We spend one hour and a half working on tutorials, exercises or projects. If you need help to get started, we will help you finding a good way for learning. You should be prepared to spend your time "doing things": just hanging around and listening might get boring, if all other people are learning on their side. There are experienced people are around and you can ask questions as soon as their arise or bring with you questions you have had during the week. During the last half an hour, we do a (simple) exercise together. We speak German, English, and a few other languages. Currently, how main programming languages are: * Python * Javascript * Java * Flutter * C++ * C * C# * PHP But you're free to learn any programming language during our Co-Learning! If you want to learn more about our Co-Learning, please have a look at our website (no frequent updates...): https://opentechschool-zurich.github.io/ If you're starting with Python, we can suggest: * Learning Python the hard way (https://learnpythonthehardway.org/python3/) (for Python 3). * The Solo Learn Python 3 Tutorial (https://www.sololearn.com/Course/Python/). * A big list of Python tutorials: https://docs.python-guide.org/intro/learning/ For Node.js: * Nodeschool: https://nodeschool.io/ For C++ * https://de.wikibooks.org/wiki/C%2B%2B-Programmierung * https://www.sololearn.com/Course/CPlusPlus/

Most of us, irrespective of diet, culture, or political affiliation, say that we care about how animals are treated and consider animal cruelty to be unacceptable. Many of us would like to contribute, in whatever ways seem feasible, to improving farmed animals' living conditions and alleviating some of their suffering. This event is about making it easier to help, through knowledge and shared understanding. 🌱 **Why is this importan**t?: Cruel but standard farming practises such as confinement cages and routine mutilations practices continue to affect hundreds of billions of sentient animals every year. The number of animals killed each year is more than the total number of humans who have *ever existed*. Many philosophers, ethicists, and researchers regard the degree and scale of the caused suffering as one of the most serious and neglected moral problems of our time. This event, which combines a structured lecture 🎙️ with a collaborative discussion 💬, is an opportunity to look more closely at some proven, effective strategies to address the problem. It will be presented by **The Humane League's** Research Lead **Giovanni Fabris** and Principal Strategist **Leo le Ster,** who will offer an inside look at how animal welfare campaigns are designed and what makes them succeed. **About The Humane League** 🌍: The Humane League is one of the most effective animal welfare organisations in the world, working to end the abuse of animals raised for food through corporate campaigns and policy change. Thanks to their work and that of their allies, cage-free hen production in the US rose from around 3% to nearly 46% over 15 years. **Helping animals beyond individual choices:** Individuals can help animals in many ways — changing their diets, donating to impactful organisations, or volunteering. Being vegan is one of the most direct ways to withdraw personal support from systems that cause animal suffering. But some of the highest-impact opportunities lie in shifting institutions and corporate policies — work that most people are entirely unaware of, and that this evening will shed some light on 💡. **Logistics** 📍: We meet directly at ETH Zurich HG E41 on Tuesday, 28 April, at 6.15 p.m. (please be on time!). After the talk, there will be a chance to discuss and socialize over vegan pizza. 🍕 **You don't have to be vegan to join:** As always, this event is ***open*** to everyone — and ***relevant*** to everyone. Whether you are fully vegan or nowhere near it, there are plenty of meaningful ways to contribute to this cause, and this evening is a good place to start figuring out what that might look like for you. 🌱

Welcome back to Papers We Love, Zurich! In this session, Daniel Galán Pascual, a PhD student in the Information Security group at ETH Zürich, will present "**A Gentle Introduction to Ownership Types in Rust**". Ownership types are what give Rust its memory safety guarantees: the compiler statically rules out entire classes of bugs (use-after-free, data races, dangling pointers) with no garbage collector and no runtime cost. Through worked examples, the talk builds a working understanding of ownership in practice, drawing on the conceptual model of "[A Grounded Conceptual Model for Ownership Types in Rust](https://arxiv.org/abs/2309.04134)" and its accompanying Aquascope tool. **Why care?** * ***For systems programmers***: ownership types are a general approach to resource management that shows up across many languages, with Rust being the most prominent industrial example. The intuition you build means finally making sense of borrow checker errors when they matter most, both in Rust and beyond it. * ***For PL and type-theory enthusiasts***: ownership types have deep connections to linear and affine type theory. Seeing them in an industrial language reveals how theory meets real-world complexity. The talk will be 45-60 minutes, followed by discussion, Q&A and snacks. No prior background in type systems or Rust is required. However, basic systems programming background will be beneficial.

Angular Zürich is back this April with two exciting talks exploring the future of Angular and modern application architecture. In the first talk, **Tomas Trajan** presents *“Embracing agentic future with Angular Skills & MCP”* He will explore how Angular is evolving in the age of intelligent, agent-driven systems, and what skills developers need to stay ahead. Expect insights into modern Angular capabilities, emerging patterns, and how MCP and agent-based approaches are shaping the future of frontend development. The second talk by **Mateusz Halada**, *“Gone without a Zone - Understanding Zoneless Angular”* dives into one of the most important shifts in Angular’s evolution. You’ll learn what it means to go zoneless, why it matters for performance and developer experience, and how to approach building applications without Zone.js. Join us for an evening of forward-looking Angular topics, practical insights, and great discussions with the community. **Agenda** * 18:00 – **Doors open** * 18:15 - 18:30 – **Intro** * 18:30 - 19:00 – **Tomas Trajan** \- Embracing agentic future with Angular Skills & MCP * 19:05 - 19:45 – **Mateusz Halada** \- Gone without a Zone \- Understanding Zoneless Angular * 19:50 - 21:00 – **Networking**

When judging morality, should we prioritize **intentions/duty** or **outcomes/results**? It introduces two influential philosophers as representatives of these approaches. * **Immanuel Kant (deontology):** An action is moral when it is done from **duty** and follows rational, universal principles (the **categorical imperative**). Certain acts—like lying—are wrong regardless of the consequences; you can’t do a wrong thing for a right reason. * **John Stuart Mill (utilitarian consequentialism):** The morality of an action is determined by its **effects**, specifically how much **happiness/well-being** it produces. Mill argues that some pleasures are “higher” than others, and that good intentions don’t redeem harmful outcomes. ## Discussion Questions 1. **The lying dilemma:** A murderer comes to your door and asks if your friend is hiding inside. Kant would say you must not lie. 2. **Can good intentions rescue a bad outcome?** 3. **The organ harvest problem:** A surgeon has five patients dying of organ failure and one healthy patient in for a checkup. Killing the one to harvest organs would save five lives, and the math works out for the utilitarian. Why does this feel so deeply wrong? Is that feeling a point in Kant's favor, or just a bias we should overcome? 4. **Do rules need exceptions?** Kant insists moral rules must be universal, with no exceptions. But most of us can imagine extreme scenarios where any rule seems like it should bend. Does the need for exceptions fatally undermine deontology, or is the strength of the system precisely that it refuses to bend? 5. **Who gets to calculate the consequences?** Utilitarianism asks us to maximize good outcomes, but we're notoriously bad at predicting consequences. If we can't reliably know the results of our actions, is it practical to base our entire moral system on outcomes? Does this uncertainty push us back toward rules and principles? 6. **Everyday morality:** Think about a real moral decision you've made recently, even a small one. Did you reason more like a Kantian (what's the right thing to do in principle?) or more like a utilitarian (what will produce the best result?)? Do most people naturally lean one way? 7. **Justice vs. the greater good:** A town can prevent a deadly plague by sacrificing one innocent person. The greater good is clearly served. But is it just? Can an action be morally right and deeply unjust at the same time? 8. **The big synthesis question:** Are these two systems actually opposed, or do they often arrive at the same answers by different paths? Is it possible that we need both: rules to guide us in the moment and consequences to evaluate systems and policies over time?
